Two heterozygous dominant parents for attached earlobes are crossed to predict the traits of their offspring. What is the ratio of attached earlobes to unattached earlobes in their offspring? A - 3:1
B - 1:3
C - 2:2
D - 4:0

A - 3:1

Explanation:

In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.

| P | p

——————-

P | PP | Pp |

——————-

p | Pp | pp |

As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.

biology is the study of life. it is the study of living organism.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
